SSM+MySQL Campus Second-Hand Trading WeChat Mini Program - Computer Graduation Design Source Code
As a computer science graduate, I am excited to share my graduation design project, which is a SSM (Spring + Spring MVC + MyBatis) based campus second-hand trading WeChat mini program. The program aims to provide a platform for students and staff to buy and sell used goods, promoting sustainability and reducing waste on campus.
System Architecture
The system architecture consists of three main layers: presentation layer, business logic layer, and data access layer.
1. Presentation Layer: This layer is responsible for handling user requests and displaying the results. It uses Spring MVC to handle HTTP requests and responses.
2. Business Logic Layer: This layer contains the core logic of the system, including user authentication, goods management, and order processing. It uses Spring to manage the business logic and MyBatis to interact with the database.
3. Data Access Layer: This layer is responsible for accessing and manipulating data in the MySQL database.
Key Features
1. User Registration and Login: Users can register and log in using their WeChat account, ensuring a seamless and secure experience.
2. Goods Management: Users can post, edit, and delete goods listings, including product information, price, and images.
3. Goods Classification: Goods are classified into categories (e.g., learning supplies, daily necessities, food, clothing) to facilitate searching and browsing.
4. Goods Review and Rating: Buyers can leave reviews and ratings for the goods they purchased, helping other users make informed purchasing decisions.
5. Order Management: The system manages orders, including order status updates, payment processing, and shipping information.
6. Payment Gateway Integration: The system integrates with a third-party payment gateway to facilitate secure transactions.
Goods Audit and Classification
To ensure the quality of goods listed on the platform, we implemented an audit process:
1. Goods Submission: Users submit their goods listings for review.
2. Audit Process: The system reviews each listing to verify its authenticity and relevance to the campus community.
3. Classification: Audited goods are classified into categories based on their characteristics.
MySQL Database Design
The MySQL database consists of several tables:
1. users: stores user information, including username, password, and WeChat ID.
2. goods: stores goods information, including title, description, price, images, and category.
3. orders: stores order information, including order status, payment method, and shipping details.
4. **reviews**: stores buyer reviews and ratings for the goods they purchased.
**Technical Details**
The system uses:
1. Spring Framework (version5.2.6) for building the web application.
2. Spring MVC (version5.2.6) for handling HTTP requests and responses.
3. MyBatis (version3.4.5) for interacting with the MySQL database.
4. MySQL (version8.0.22) as the relational database management system.
5. WeChat Mini Program SDK (version2.1.0) for integrating with the WeChat platform.
**Conclusion**
The SSM+MySQL campus second-hand trading WeChat mini program is a comprehensive platform that provides a secure and efficient way for students and staff to buy and sell used goods on campus. The system's architecture, key features, and technical details demonstrate its scalability, reliability, and maintainability. As a computer science graduate, I am proud to have designed and developed this project as my graduation thesis.
